This invention relates to pumps of that t in which fluid pressure is.utilized to l1 liquid step by step through va series' of 'connectedcylinders, the objecti of the invention being to simplify theconstruction and provide an inex nsiveapparatus which will operateelicient y to raise the liquid .and will be automa-tic in its actionafter having been once startedi The device is intended more particularlyfor use'in deepwells but it may, of course, be used in relativelyshallow wells, the number of the cylinders employedA and the distancebetween the cylinders beingdetermined by the depth ofthe well and thepressure to be utilized. The invention is illustrated in theaccompanyingdrawings and will be hereinafter novel features being subsequentlyparticuthe rappended claims.

As has been stated, any number of 'cylinders may be employed, but in theaccompanying drawings I have illustrated four cylinders and havenumbered the same 1, 2,

3 and 4, respectively for convenience, in setting forth the operation.The lowermost cylinder 1 is located at such a depth that it will besubmerged, as' shown in Fig. 1, and will lill with the water'I or otherliquid to be raised by the action of gravit An inlet pipe 5 iStted inthe lower en of the cylfully set forth, the' through the ca im. semi n.101,5os.

sure fluid.- This airpipe'? is .provide ad-4 pper endof jacent eachcylinderwlth a branch. 8 leadf ing laterally over the cylinder andl thendownto'communicate with a port or assage 9 leading through the topf cap10 o the cylinder into an air chamber 11 formed in t e lower end of thecap. A port or passage 12 leads from the top of the air chamber-1l intothe upper end of the r 13 of the cylinder. An exhaust port or assage 14is also, formed in the cap 10 and t is exhaust port leads from the topof the chamber 11 to the outside air in the well, as will be understoodupon referenceL to Fig. 3. To control the flow of air to and from thepumpin chamber, a rocking valve 15 is rovided, t e said valve beinsecured upon t e lower end of a rock sha t 16 which is journaled in thecap 10 of the pump cylinder and extends vertically through the same, theupper end of the said' rockv shaft being equi ped with an armature 17 ofany approve construction. The valve 15 is in the form of a late littingclosely but slidably against t e under side of a ported cage 18 fittedin the air chamber, a recess or groove 19 being formed in the upper sideof the valve to register at pumpmg cham times with the ports 20 or 21 inthe said cage so that the flow of air will be directed to or cut oli'from the exhaust according to the position of the valve;v secured withinthe air chamber 11 b or other closure 22 rthreaded Vinto tlie lower endof the said chamber, as clearl shown in Figs. 3, 7 `and 8. When the vave is in.

the position shown in Figs; 3 and 8, the passage 12 will be connected'with the exhaust passage or '(port 14 and the air within the pump cyliner may escape, 'thereby'permit tingv the entrance of liquid butl whenthe valve is shifted to the position -shown in Fig. 7, the exhaust portor passage will be closed and the paage 12 will be in comm-unicationwith the inlet port 9 vthrough the The ycage 18 .is

. outlet or by-pass 28 is a flap check valve 3() air chamber 11, itbeing understood that the said port 9`discharges directly into the airchamber so that t-here is always pressure within said chamber whichholds the valve up so that` it will be seated snugly against the underside of the top plate of the cage 18.

A bracket 23 Orother suitable support is secured `around the pipe Gabove the cylinder, and this bracket carries a pair of electromagnets 24and 25 which are disposed adjacent to but at opposite sides of thearmature 17 and serve to attract the said armature 'and\ther'eby rockthe shaft 16 and set the valve 15 in open or closed position accoi-dingto which magnet is energized.

'. tu-dinally of the 'cylinder at one side of the 'pumping chamberandcommunicates at its lower end with'the said chamber 26 and at its upperend with a passage or port 29 through the upper capv which leadsdirectly into the pipe 6. In the lower `end ot' the which is normallyseated upon a shoulder 3l provided in the said passage 28. Over' theinlet V5 of the lowermost cylinder and over theupper end of the pipe 6in each of the upper cylinders is a flap check valve which is normallyclosed across the upper end ot' the inlet port, asshown clearly in Fig.4. It will also be noted that this-check valve 32 is larger than thevalve, 3() and.y consequently, when it is raised its t'ree edge williinpinge against the lower end of the wall of the cylinder between thepumping chamber 13 and the by-pass or outlet 28, thereby cutting otf theliquid from access to the said passage 28 and directing it positivelyinto the pumping chamber. It will also be readily understood fromthedescription thus far given that the entering liquid flows into andtills`the pumping chamber 13, and fluid under pressure is tlTen admittedthrough the passage 12 into the top VIAof the pumping chamber. whereuponthe pressure exerted upon the liquid by the said Huid will expel theliquid .so that it will How from the lower end of the chamber 13 int-othe by-pass 2S and will pass directly therefrom into the next cylinderabove or be held therein by the check valve 3() until the next stage ofoperation ot the apparatus. When the pumping chamber 13 is filled withliquid. the pressure upon the check valve 32 will be neutralized so thatthe weight of the valve will then cause it to again be seated.

Mounted in the lower' end of the pumpving chamber 13 is an automaticswitch consisting of a tubular body which may be .of metal or any othermaterial having slitticient durability. rl`his body-'V33 ishinged,

as shown at 34, to one ,side of the pumping chamber and at its free endis provided with a hollow spherical head35 so that suthcient buoyancywill be imparted to the device to permit it to readily swing upwardly asthe Water enters :the cylinder. fithin the tubular body 33 is secured ahollow glass bulb 36 having wires 37 fused .in its respective ends withtheir own ends spaced apartto .wires 37, while in another position,-which is the position illustrated in Fig. 9, it will be away from thesaid gap and the electric circuit will be broken. Conductors 40, whichare suitably insulated, are attached to the respective Wires '37 andextend through the wall of the cylinder .to be \cariied in a cable 41suitably ysupported on the side of the cylinder.

The uppermost cylinder is connected directly with a discharge pipe 42which extends to any desired point of use and is equipped with a.cut-off valve 43 so that the outflow may be regulated or entirely cutott when desired so that the operation of the puiiip maybe controlled.

Above the ground and at the mouth of the well or at a point remotetherefrom, as may be pref-erred, is disposed a housing 44 in which aremounted solenoids 45 and 46 which constitute. part ot' the controllingmechanism, current being supplied from a local generator or from trunklines, indicated at 47 in Fig. 10. The cable 41 and a similar cable 48carry the wires whereby the current is led from the feeding trunk linethrough the electro-magnets 24 and 25 and the solenoids 45 and 46 backto the outlet trunk line as well as the wires which are connected withthe float switches 33. Referring particularly to Fig. 10, it will benoted that a conductor 4f) extends downwardly through the well and has abranch 5() leading -to the electro-magnets 24 and 25 over the respectivecylinders. Each branch 50 is divided so that it serves as part of theenergizing circuit for each of the electromagnets. The return from themagnet 24 ot' the cylinder 1 is through a conductor 51 which extends tothe mouth of the well and thence to a terminal 52 which is adapted to beengaged by the switch arm 53 extending across the core of the solenoid45. This return Wire 51 is also connected with the return conducto-rs 54of the magnets 25 at the cylinders 2 and 4. The conductor 49 is exwillbe seen at once,

memos connected to the power line. Should theS water be forced fromcylinder 1, the float switch 33 will swin downwardly so that the circuittherethrough will be closed and the solenoid 45 energized to attract theswitch arm' 53 and thereby close thc circuit through the conductor- 51.The electric connectiony between the wires 37 in the float switch, itserve to complete the initial circuit through the conductors 49 and 55which are connected. directl with the trunk lines. When the solenoi 45iis energized and the switch `52, l53 thereby closed, a circuit is alsoIcom leted through the conductors 51 and 49 so that the closing magnet24 of the cylinder 1 and the opening magnets 25 of the cylinders 2 and 4will be energized, the air being 'consequently caused to exhaust fromcylinder 1 and being admitted to the cylinder `2, whereupon liquid maagain flow an the liquid which has been admitted V`to the cylinder 2will be expelled and driven into the c linder 3. Whenthe liquid entersthe cylin er 1, the float switch 33 will, of course, be raised and thecircuit through the same broken and this condition will ex- 1st untilthe water is driven from the cylinder 2, whereupon the float switch insaid cylinder will drop and a circuitv will be c osed through theconductor 56 connecting said float switch with the closing magnet 24 ofsaid cylinder and theconductor/57 conl by branches 61 with noid 46 and,consequently,

' of the cylinders necting said switch with the winding ofthe -soleno1d46, which winding is connected with the outgoing trunk line in the samemanner as the winding o f the solenoid 45 is so Iconnected. When thesolenoid 46 is energized, the switch arm 58 is caused to engage thecontact 59 and thereby close a circuit through the conductor 61(1) whichis connected t e o nin ma ets 25 of the cylinders 1S pe g gn fluid underressure will be admitt inders 1 and) 3 and the li said cylinders intolthe cylinders 2 and 4, respectively. This action, of course, isidependent on the hand switch 62 being in the to cylposition illustratedin Fig-10. If th'e said.

switch be in contact with the terminal 63, the conductor 57 will beconnected through the conductor 64 directly with the trunk line insteadof with the windingof the solethe said-solenoid will not be energized.The float switches 33 3and 4 are both connected by conductors 65 withthe closing magnet 24 of the respective cylinders and are connected bybranches 66`directly with the conductor 64. When. these float switchesof the vcylininto and fill the cylinder 1- and 3, whereu on the' quidexpelled from and will be highly ders 3 and 4, therefore, are lowered,the solenoid 46 will not be energized. It will thus be seenthatcylinders 1 and 2 are thc controlling cylinders nd that allcylinders above cylinder No. 2 may be equipped in the same manner as thecylinders 3 and 4.

In the lowermost cylinder, which is No. 1 in the present illustration, Iprovide an air check valve which will operate automatically to admit theair when the liquid is to be discharged but will seat when liquid isentering so that the inflow of liquid will not be retarded or checked bythe pressure fluid. This valve is shown in Fig 8 and includes a cage 67provided at its upper end with a nipple 68 whereby it may be threadedinto the end of the passage 12 and provided at.

its lower end and in its-sides with openings 69 to permit the liquid toreach the float 70 constituting the body, of the valve. This float 70has a valve stem 71 secured in and projecting from its vupper end andthe upper extremity of this stem is formed with or secured to a cone'72adapted to seat in the nipple 68 and thereby cut off inflow. The cage 67is furnished w1th'a top plate 73 which serves as av guide for the stem71 and also as a support for the conical valve head 72 when the latteris in its lowered open position'. Some of the openings 69 are arrangedin the extreme u per end ofthe cage above the plate 73 so t at theoutflowing air will not act upon the float 70 to prematurely seat thevalve but may pass around the valve head and by its pressure thereonmaintain the same in open position until the pressure fluid has allescaped. The rising liquid, however, will have ready access through thebottom of the ca e to the float 70 and will liftthe float so t at thevalve head 72 will be driven into engagement with its seat and theliquid thereb prevented from filling the passage -12, air c amber 11 andexhaust port 21. When the controlling valve I5 is shifted lto admit airfromthe air supply, the valve IHS lli)

head `72 will Vbe -unseated and the desired livered on each dischargestroke in the cyll inder.

From the foregoing description, taken in ,y connection with theaccompanying drawings,

it will be seen that I have provided an exceedingly vsimple apparatuswhich will operate automatically after having been primed eflicient fordelivering aV supply offliquid. 'lhe admission and discharge of liquidin the alternate cylinders is synchronized throughout the system so thatthe lifting of the liquid will proceed efficiently, and no cylinder willchoke the operation of any other cylinder nor be choked thereby. By thevproper use of the switch 62 the apparatus may be easily primed aftervinstallation has been completed, because of the presence of the fioatswitches 33 in each 'cylinder and the fact that the switch arms-superposed cylinder, means for admitting iluid under pressure to theupper ends 0f the cylinders, a switch in the lower end of each cylinderarranged' to be raised toinopera# tive position by the 4inflowing liquidand to move downwardly to operative position 'when the liquid isdischarged, a valve at the upper end of each cylinder controlling thein-iiow and exhaust ot fluid under pressurethereto,
